Each module provides two kind of APIs: a procedural one and an object oriented one. Both are actually identical and described in the corresponding document.
Note: All input strings must be in UTF-8 encoding. All output strings are also in UTF-8.
Example #1 Example of using the procedural API
<?php$coll = collator_create('en_US');$result = collator_compare($coll, "string#1", "string#2");?>
Example #2 Example of using the object-oriented API
<?php$coll = new Collator('en_US');$al = $coll->getLocale(Locale::ACTUAL_LOCALE);echo "Actual locale: $al\n";$formatter = new NumberFormatter('en_US', NumberFormatter::DECIMAL);echo $formatter->format(1234567);?>
